Thanks for that.Sorry to hear about your faulty sensor, sadly you won’t be able to get it working again but all is not lost.ok, Don’t throw the away as abbot will want it back to do any necessary checks they will also send a replacement .
They asked for the serial number and also said that I’d need to send it back.I find they don't ask for the sensor back. They just need the serial number, which is available on your reader.
Actually, my last sensor gave up the ghost four hours ahead of schedule, but even I didn't have the nerve to ring for a replacement. I self fund, so that's nearly a quid I'll never see again.
